The innovative Grade 100 open ring shackles TWN 1847 are used as a fixed size connection of lifting chains with sling components to assemble chain slings.
For the correct assignment of the nominal size of the suspension links, the ring shackles are provided with a diameter indication forged on the body.
The ring shackles provide an optimized, almost non-interchangeable and safe connection option for the simple assembly of chain slings.
The manufacturing and testing requirements are based on the ASTM A952/A952M, DIN EN 1677-1 and ISO 8539, under consideration of Grade 100 working load limits.
